Each asset will have a space value that is used to automatically calculate how much stuff can be carried by a person, barge, boat, etc. or stored at the base camp or town hall.
Assets distributed by the game will be limited in number. Crafted items will not be limited, the economy will keep these under control.
For example, a Basic Hut takes up 250 squares of property space and has 250 cubes of space. The Basic Hut is tokenized, but can be upgraded to a larger structure in order to store more inventory and unlock additional property features. When you upgrade a structure, you will be issued the next level token and may sell your old token to a new player.
Some salvaged items are repairable and require other salvaged items to repair. This is where professions come into play. Everything in the game is usable to at least one profession. Common items are repairable by anyone, however, hard to find and rare items are only repairable by specific professions.
Anyone may buy, sell or trade any item.
